An electronic camera that creates an image file by processing image data
obtained through an image-capturing operation, includes: an
image-capturing unit that generates the image data by capturing a subject
image; a data extraction unit that sets an image plane range
corresponding to an image portion of the image data and extracts data of
the image portion in the image plane range; a data insertion unit that
writes data of a predetermined specific image over the image plane range
of the image data and generates data of a processed image; and a file
creation unit that creates an image file by storing the data of the
processed image into an image data area of the image file, which is
referenced as image data and storing the data of the image portion into a
non-image data area of the image file which is not referenced as image
data.
